PEN-HOLDER.

SPECIFICATION forming part of Letters Patent No. 446,646, dated February17, 1891.

Application filed April 12,1890.

To all whom it out concern.-

Be it known that I, FREDERICK J. KALDEN- BERG, a citizen of the UnitedStates, residing at Tarrytown, in the county of \Vestchester and Stateof New York, have invented a new and useful Improvement in Pen-Holders,of which the following is a full, clear, and exact description,reference being had to the drawings accompanying and forming a part ofthe same.

My invention relates to improvements in the manufacture of pen-holdersof that class made of expensive material, as pearl, &c.; and the objectof my improvement is to provide means whereby the small pieces of pearl,which heretofore have been of no value in the manufacture ofpen-holders, may be utilized not only to produce a holder of equalsuperiority, but one of far greater beauty and ornamental finish.

In the ordinary manufacture of pen-holders out of pearl the handle hasbeen made of a single solid piece of the required full length turneddown to the proper shape. Now, it is well known in the trade that onlyabout forty per cent. out of a case of pearl is available for making upinto pen-holders, from the fact that only pieces of a certain length canbe used. Consequently the manufacture of pearl holders is necessarilylimited.

The purpose of my improvement is to provide a means for using up theshorter pieces of pearl for pen-holders-such pieces as have heretoforebeen considered useless for this purpose-thereby effecting a greateconomy in the use of this valuable and ornamental material. Toaccomplish this object,I form the pen-holder out of a short piece ofsolid pearl combined with slabs or thin pieces of pearl united together,using in the manufacture such pieces of solid pearl as have hithertobeen valueless for this purpose.

In the accompanying drawings, which clearly illustrate the novelfeatures of my improvement, Figure 1 is a side view of a pen-holderenlarged, showing the same com posed of one solid piece of pearlcombined with two sections formed out of slabs of pearl. Fig. 2 is aview, partly in elevation and partly in section, showing more fully theconstruction of the ends of the holder, and Fig. is a Serial No.347,718. (No model.)

side view of a pen-holder composed of one solid piece of pearl combinedwith but one section made of slabs of pearl.

There the required length of the penholder is attained by combining twoformed sections with the solid piece of pearl, the very short pieces ofpearl can be utilized for its center part.

Referring first to Figs. 1 and 2, the penholder is shown as composed ofthree parts united together, as a, Z), and c. The central section b isof a single piece of pearl, and the two end portions a and c are made upof thin slabs of pearl united together. In the drawings these endsections are shown as composed of alternate strips of pearl of differentshades or color, as a dark strip 6 and light one f, so that a beautifuleffect is produced by the combination of contrasting colors.

In the construction of the holder the solid piece of pearl b is formedwith a prolonged and reduced end portion g, tapering to ablunt tip, andon this reduced part are cemented thin slabs of pearl h, t', and j,being in number as many as are necessary to cover the same. These narrowslabs are fitted up closely to the shoulder k on the piece I). Theopposite end of the pearl piece I) is also provided with a reduced endportion 2, on which is fitted a tube m, preferably made of metal, andwhich is secured thereto by one or more pins or rivets n. The tube isthen covered by narrow slabs f o, of pearl, the same being secured bymeans of cement. As a better method of fastening on the slabs, I preferto interpose between the tube and slabs a strip of cloth or othersuitable textile material 15), which may also be cemented to the tube,or the strip may be wound around the same, and then the slabs cementedto the cloth. The tube m is made to project beyond the slabs to form anend q, on which is fitted a band or ring 0', preferably made ofmetal,leaving still a reduced end portion to receive the nose 5. Afterthe holder is formed by the cementing on of the slabs it is thensubmitted to the action of a suitable grindinganachine until the surfacethroughout is made uniformly smooth and it is reduced to a perfectrounded shape.

In Fig. 3 is shown a pen-holder composed of a single piece of pearl withbut one end portion formed 06 the narrow slabs of pearl. In this casealonger piece of solid pearl must be used for the section Z). Theconstruction of the section a is the same as that heretofore describedfor Figs. 1 and 2.

Having now described the nature of my invention, What I claim as new,and desire tosecure by Letters Patent, is

1. In a pen-holder, a solid piece or section provided with a prolongedand reduced end, and a tube secured thereon and covered With narrowslabs, the said tube projecting be-
